| Error scenario | Recovery mechanism |
|----------------------------------------|----------------------------------------------------------|
| Network timeout | Retry chunk with exponential backoff (up to maxRetries) |
| 403 / 403 Forbidden | Abort upload; prompt user to re-authenticate. |
| 500 Internal Server Error | Retry chunk (assume transient). |
| Browser tab closed | Resume from last completed chunk on next session. |
| Chunk checksum mismatch (ETag diff) | Re-upload chunk. |
| Metric | Value / Observation | |----------------------------|------------------------------------------------------------| | Memory usage | ~10 MB overhead + size of one chunk (5 MB default) = ~15 MB | | CPU impact | Low except during hashing (if checksum enabled). | | Max throughput | S3-limited; observed ~50–200 Mbps on residential fiber. | | Large file stability | Successfully tested with 400 GB files (24-hour upload). | | Resume reliability | >95% recovery rate after network disconnect. | internet archive html5 uploader 1.7.0

Internet connections are unreliable. This version includes an exponential backoff algorithm. If the server returns a 503 error (service unavailable), the uploader waits 2 seconds, then 4, then 8, up to a maximum, retrying the operation without user intervention.
